No. You need it in the run library path, not just the link library path.

Look in m4/R.m4 or aclocal.m4.
We have no idea where you installed g77, but that is not a standard place

But not even /usr/local/lib (the usual place for an install of gcc from
sources) is in the standard Solaris path AFAIR.
